ENGLISH ABSTRACT: The development time, survival and fecundity of Trichogrammatoidea cryptophlebiae
Nagaraj a, an egg parasitoid of false codling moth, Cryptophlebia leucotreta Meyr., on .
citrus were determined at 15,20,25 and 30°C. Using these values the intrinsic rate of
increase (rm), mean generation time (T) and net replacement rate (Ra) were estimated
at the respective temperatures. In addition, the data were used to estimate the
minimum temperature required for development. The rmincreased from 15 (0,042) to
20°C (0,088) and then gradually decreased from 25 (0,069) to 30°C (0,012). The Ra
was highest at 20°C (3,116 females/female), followed by 15°C (2,607
females/female), 25°C (1,894 females/female) and 30°C (1,092 females/female). T
decreased as temperature increased from 7 days at 30°C to 22,79 days at 15°C. The
estimated minimum temperature for development was 7,65°C which implies that this
wasp should be able to survive and reproduce under normal winter conditions in the
Western Cape.
